What Is Podcasting?

Podcasting is distributing audio or video content via RSS 2.0, or (less commonly) Atom. Podcast clients are available, like Juice (http://juicereceiver.sourceforge.net/index.php), CastPodder(linux) (http://www.castpodder.net/), or iTunes (http://www.itunes.com/) that allow listeners to subscribe to your RSS/Atom feed and automatically download your content to their portable audio players as it becomes available.
How It Works
  1. Create audio or video that you want to share (usually MP3 or MP4)
  2. Upload the file to a server
  3. Link to the file in a post in your weblog
  4. Wordpress automatically Includes a link to the file in your RSS/Atom feed
  5. Listeners "subscribe" with podcast client application to your RSS/Atom feed and download new files automatically.
WordPress creates all the necessary links for you!
